Description

WIPE-ON LABEL APPLICATOR FOR FRUIT OR VEGETABLES
AND ASSOCIATED METHODS
The present invention relates to labelers, and, more particularly, to a wipe-on labeler.
Labels are typically applied to fruits and vegetables in packing houses. The speed at which these labels are applied is important because the fruit must be packed and shipped quickly so that the shelf-life in stores will be as long as possible. Generally, the speed at which the labeler dispenses the labels is a limiting constraint. This constraint also results in an inE~fficient use of other equipment and personnel in the packing house, thus increasing the overall cost of packing fruits and vegetables. Accuracy of applying the labels is also another important factor. Ideally, a hit rate of 100% is desirable. When the hit rate is less, a label is not successfully applied to a fruit.
Packing house profitability is adversely affected when a label that would have permitted a higher selling price is not applied to fruit otherwise capable of commanding such a higher price.
Labelers generally apply pressure sensitive labels using a continuous label strip carrying a , . CA 02307152 2000-04-28 plurality of labels for application to the fruit as it is conveyed past the labeler. However, many existing labelers require stiffness in the labeling material, and consequently, paper or laminated labels have to be pre-cut to lay properly on the fruit. Accordingly, vinyl labels may be preferred because they are thin and flexible and more easily conform to any fruit shape, and the adhesion to the fruit is thus better.
Unfortunately, applying such labels at high speed may be difficult.
A number of techniques have been developed to attempt to increase the speed and accuracy of labelers.
For example, U.S. Patent No. 4,217,164 to La Mers discloses a bellows type labelling system using pressure sensitive labels attached along a label strip that includes a line of weakness down its middle forming separable~halves, with the labels attached over both halves. The label strip is pulled along a plate towards a V-shaped notch in one edge of the plate. At the notch, the two halves of the label strip are drawn through the V-shaped notch with each half over a different side of the V. This causes the two halves of the label strip to follow divergent paths from each other, and also from the label, forcibly releasing the label.
A significant advance in the art of applying vinyl labels is disclosed in U.S. Patent No. 5,829,351 to Anderson et al., inventors of the present invention.
The disclosed labeler includes a bellows drive gear and a cassette drive gear spaced apart and each rotatably supported in a housing. A stepper motor is mounted in the housing and has an output shaft. A first drive gear is affixed to the shaft and engages the bellows drive gear. A second drive gear is affixed to the shaft. A drive train engages the second gear and the cassette drive gear. Because there is a direct connection between the drive of both the bellows wheel and the cassette, a full bellows cycle is available to accurately effect the transfer of a label from the label strip to the end of the individual bellows.
U.S. Patent No. 5,660,676 to Brooks discloses a wipe-on labeler with a peel blade for separating the labels from the carrier strip. Similiarly, U.S. Patent Nos. 3,793,114 and 4,017,350 to Thomas disclose a wipe-on labelling machine that dispenses adhesive labels from a label strip that includes supply and collector reels, a pivotal rocker ar<n carrying an application roller, and an adjustable guide member disposed between the reels and the roller so that the labels on the label strip are peeled therefrom by movement of the label strip around the guide member. A pawl is rockable about the same pivot axis as the pivotal rocker arm for applying pressure against the label strip. The pawl provides a ratcheting index technique for advancing the labels. Accordingly, this labeler is difficult to operate at higher speeds because the ratcheting pivotal rocker arm must swing through a predetermined working stroke before'a label is advanced.
Other wipe-on labelling machines that dispense adhesive vinyl labels include labelers manufactured by Hurst Labeling Systems, PROLABEL, and Booth Auto Pak. The PROLAHEL labeler includes an adjustable speed D.C. stepper motor, and an electronic eye sensor for detecting fruit location. These labelers feed the label strip over a flat edge of the applicator arm, which unfortunately may lack accuracy in placing the labels onto the fruit.
In view of the foregoing background, it is therefore an object of the present invention to provide a labeler and associated method that improves the speed _ , and accuracy at which labels are applied to fruit or vegetables.
This and other advantages, features and objects in accordance with the present invention are provided by a wipe-on labeler comprising a frame, a label cassette connected to the frame for dispensing a label strip including a carrier and a plurality of labels adhered thereon, a conveyor for advancing fruit along a predetermined path of travel, a label applicator arm pivotally connected to the frame adjacent the label cassette, and a label feeder for advancing the label strip along the label applicator arm to a free end thereof. Because the fruit labeler is a wipe-on labeler, it is less complex than rotary and reciprocating type labelers, and can accordingly place labels at a relatively high speed.
The label applicator arm pivotally extends outwardly from the label cassette, preferably albng the predetermined path of travel so that the free end contacts the fruit. The label applicator arm preferably has a V-shaped notch in~the free end for separating from the carrier the label to be applied to the fruit as the carrier passes through the V-shaped notch, and is divided into two carrier waste portions.
The carrier waste portions are withdrawn by the label feeder.
The label applicator arm also preferably includes a resilient roller attached to the free end adjacent the V-shaped notch for pressing against the fruit. The V-shaped notch advantageously removes the label from the carrier, and the resilient roller presses the label onto the fruit as it rolls over the fruit. This allows the dispensing of vinyl labels, which conform to fruit better than paper or laminated labels. Consequently, the accuracy or hit rate of the labeler according to the present invention is improved . CA 02307152 2000-04-28 when vinyl labels are dispensed because they more readily conform to the shape of the fruit.
The label feeder also preferably includes a pair of take-up wheels for respectively taking up the pair of carrier waste portions after being split by the V-shaped notch. Because the carrier halves both support the label, if the labeler dispenses a label when there is no fruit, the label desirably stays on one of the waste portions and is discarded.
The label strip preferably has at least one edge with a predetermined profile, and the label feeder includes a dispensing wheel having a similar corresponding profile.
The label applicator arm preferably includes at least one spring for biasing the label applicator arm toward the conveyor, and a damper for damping pivotal movement .thereof when contacting fruit having significant size differences. These above described aspects according to the present invention allow the speed of the labeler to be significantly faster than conventional wipe-on labelers.
Another aspect of the present invention relates to a method of applying labels to fruit using a labeler having a frame, and a label applicator arm pivotally connected to the frame and extending outwardly along a predetermined path of travel so that a free end of the label applicator arm contacts the fruit. The method preferably includes the steps of advancing a label strip using a label feeder along the label applicator arm to the free end thereof, and separating from a carrier of the label strip a label to be applied to the fruit as the carrier passes through a V-shaped notch.

The present invention will now be described more fully hereinafter with reference to the accompanying draw~.ngs, in which preferred embodiments of the invention are shown. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. Like numbers refer to like elements throughout.
Referring initially to FIG. 1, a perspective view of a fruit labeler, generally indicated at 10, is described in accordance with the present invention.
The fruit labeler 10 includes a frame 12, a label cassette 14 connected to the frame for dispensing a label strip 16, a label applicator arm 18 pivotally connected to the frame adjacent the label cassette, and a label feeder 20 for advancing the label strip along the label applicator arm to a free end thereof. The label feeder is generally indicated by reference 20, which will be described in greater detail below.

_7_ The frame 12 is supported and advanced by a conveyor 22, which advances fruit 24 along a predetermined path.of travel as will be appreciated by those skilled in the art. The label applicator arm 18 extends outwardly from the label cassette 14 along the predetermined path of travel so that the free end of the label applicator arm contacts the fruit 24. The conveyor 22 preferably has conventional cradles 26 for holding and positioning individual fruit 24. Other methods of advancing fruit 24 along the predetermined path of travel are acceptable, as will be readily appreciated by one skilled in the art.
The label strip 16 has a carrier 30 and a plurality of labels 32 adhered thereon, as best shown in FIGS. 2 and 3.' The labels 32 are preferably vinyl since vinyl labels are thin and flexible and more easily conform to a variety of fruit shapes than paper or laminated labels. The adhesion to the fruit 24 is better because of this conformity.~~ However, application of the labeler 10 according to the present invention is not limited to vinyl labels, as will be readily appreciated by one skilled in the art.
Each of the labels 32 has a front face 32a with a decorative design or other identifying indicia printed thereon. The label striF 16 includes a separation line 34 along its length at a middle portion thereof. Preferably, the separation line 34 is perforated but may be a line of weakness as well. The label strip 16 also has at least one edge 36 with a sinusoidal or other predetermined profile which facilitates accurate positioning, as will be described in more detail below.
Now referring additionally to FIGS. 4-6, the labeler 10 is described in greater detail. The label _g_ feeder 20 advances the label strip 16 along the label applicator arm 18 to the free end thereof. The label feeder 20 includes.a cassette gear 48, a dispensing wheel 50, a pair of take-up wheels 52, and a drive shaft 54 coupled therebetween. The cassette gear 48 is rotated by a stepper motor 60. The stepper motor 60 is also part of the label feeder 20, and is activated or energized for rotating the cassette gear 48 responsive to a fruit sensing switch 62 positioned adjacent the conveyor 22. The fruit sensing switch 62 detects the approach of fruit 24 in the cradles 26 on the conveyor 22.
The stepper motor 60 is mounted within a housing 66 attached to the frame 12, and has an output shaft 68 with a drive gear 70 attached thereto. The drive gear 70 meshes with a first idler gear 72 rotatably mounted in the housing 66. A second idler gear 74 is attached to the idler gear 72 and meshes with a cassette drive gear 76. The cassette drive gear 76~is rotatably mounted in the housing 66 with its teeth projecting through and above a protective cover secured to the top of the housing to engage the cassette gear 48 within the frame 12. To accommodate labels of different sizes, the second idler gear 74 is removably secured to the first idler gear 72 so that a gear with the number of teeth necessary to advance the label strip 16 the proper distance may be installed, as will be readily appreciated by one skilled in the art.
The cassette gear 48 is affixed to the drive shaft 54, as is the dispensing wheel 50 and the pair of take-up wheels 52. The dispensing wheel 50 has a predetermined profile corresponding to the profile of _g_ the label strip 16. More particularly, the dispensing wheel 50 has a depressed center defined by a pair of opposing sinusoidal side walls 80. The profile edges 36 of the carrier 30 are formed with a shape complementary to and engageable with the sinusoidal side walls 80.
The label strip 16 is wound on a core 82 which is rotatably supported on handles 12a formed on and extending upward from the frame 12. The label strip 16 is trained around a guide pulley 84 rotatably carried on a tension arm 86 which is loosely carried by the drive shaft 54. A second roller 88 rotatably carried by the tension arm 86 assures the label strip 16 engages the side walls 80 of the dispensing wheel 50. A stepped shaft 90 extends across and is non-rotationally secured to the frame 12. A full diameter section of the stepped shaft 90 is engageable by the guide roller 84 to assure the carrier 30 remains within the side walls thereof. The full diameter section of the stepped shaft 90 also limits the downward travel of the guide roller 84. The guide roller 84 is biased downward by gravity to trap the label strip 16 therebetween, and stop momentum of the label strip and to maintain tension therein. As the label strip 16 is dispensed, it passes over a set of rollers 85 to provide a non-restricting path to the free end of the label applicator arm 18.
To reduce the amount of bouncing of the label -applicator arm 18, particularly when the arm is dragged over two successive fruits having a significant size difference, biasing means and a damper 73 are connected to the label applicator arm 18. In one embodiment, the biasing means preferably includes a pair of springs 71 connected between the label applicator arm 18 and the frame 12. Depending on the amount of bias desired, only one spring 71 may be used. Other methods of biasing the label applicator arm 18 are acceptable, as will be readily appreciated by one skilled in the art.
The damper 73, may also comprise a dashpot which cushions or dampens movement of the label applicator arm 18 to avoid damaging the fruit 24 when a label 32 is applied thereto. In another embodiment, the damper is provided at least one spring adjacent one of the bias springs 7i, and its size is about half the length of the bias spring, but larger in diameter. In an alternative embodiment of the label applicator arm 18, the biasing means, are provided without the damper 73.
As stated above, the free end of the libel applicator arm 18 includes a V-shaped notch 40 formed by. edges 40a, 40b to split the carrier 30 of the label strip Z6 along the longitudinal separation line. The V-shaped notch 40 separates the labels 32 from the carrier 30 as the carrier passes over the respective edges 40a and 40b, as best shown in FIG. 6. As the label 32 is separated from the carrier 30, the respective carrier waste portions 30a, 30b pass briefly underneath the label applicator artn 18 and return along the upper surface on opposite sides of the label strip as shown in FIG. 5.
A resilient roller 41 is connected to the free end of the label applicator arm 16 via extension 43 for pressing separated labels 32 onto the fruit 24.
The roller 41 has an inverted V-shaped region which corresponds to the V-shaped notch 40 in the label ' " CA 02307152 2000-04-28 applicator arm 18. The roller 41 is preferably a soft material, such as rubber, so as not to damage the fruit 24.' As the label 32 is separated from the carrier 30, the roller 41 ensures that the separated label has adequate pressure for adhering to the fruit 24.
Each half of the separated carrier, i.e., the carrier waste portions 30a and 30b, pass along the upper surface of the label applicator arm 18 and around guide rollers 92 rotatably mounted by a shaft 94. Each waste portion 30a, 30b passes between the guide rollers 92 and the take-up wheels 52, and passes over the top of the take-up wheels. The take-up wheels 52 include a series of peripheral projections 98 which penetrate the respective carrier waste portions 30a, 30b of the carrier 30. A wedge 104 secured to the inside of each side of the frame 12 separates the respective carrier waste portions 30a, 30b from the projections 98 on the respective take-up wheels 52. w A bar 106 spans one end of the frame 12 and is engageable with a hook (not shown) formed in the housing 66. The bar 106 has enlarged diameter ends, the transition to which tends to center the housing 66 as it is connected to the frame 12. A spring-loaded detent (not shown) is mounted on each side of the frame 12 and engages a recess on the frame to releasably retain the label cassette 14 in place. The label cassettes are interchangeable so that one cassette can be loaded off-line with a reel of label strips 16 while another cassette is operatively engaged with the labeler 10 to apply labels to the fruit 24.
Once the stepper motor 60 has been activated by the fruit sensing switch 62, the stepper motor accelerates from standstill to a rotational speed which causes the velocity of the labels 32 to match the speed at which they will be dispensed. Matching the speed can be determined by counting the rotations of an idler gear (not shown) engaging the conveyor. when the stepper motor 60 is deactivated, the labels 32 decelerate to a standstill. The acceleration or ramp-up of the stepper motor 60 from standstill, which is initiated by closing the fruit sensing switch 62, is a function of the speed of the conveyor 22, the distance between the cradles 26 carrying the fruit 24, and the maximum tensile force to which the label strip 16 may be subjected.
Another aspect of the present invention relates to a method of applying labels 32 to fruit 24 using a labeler 10 having a label applicator arm, l8 pivotally connected to a frame 12, and extending outwardly so that a free end of the label applicator arm contacts the fruit. The method~preferably includes the steps of advancing a label strip 16 along the label applicator arm to the free end thereof, and separating a label 32 from a carrier 30 of the label strip to be applied to the fruit 24 as the carrier passes through the V-shaped notch 40 in the free end of the label applicator arin. The labeler 10 includes a dispensing wheel 50 having a predetermined profile, and the label strip has at least one edge 36 with a corresponding profile of the dispensing wheel. The method further includes the step of engaging the profile of the label strip 16 to the profile of the dispensing wheel 50.
Because the label strip 16 and the dispensing wheel 50 have corresponding profiles, a precise and repeatable location of the label 32 is known every time, which improves the accuracy of dispensing labels to almost 100%. This avoids the use of a more costly electronic edge detector for providing a location of the labels. With the label applicator arm 18 including at least one spring 71 for biasing the label applicator arm toward the conveyor 22, and a damper 73 for damping movement of the label applicator arm when dragged over sequential fruits 24 having a significant size difference, the speed of the labeler 10 is significantly faster than conventional wipe-on labelers.
Many modifications and other embodiments of the invention will come to the mind of one skilled in the art having the benefit of the teachings presented in the foregoing descriptions and the associated drawings. Therefore, it is to be understood that the invention is not to be limited to the specific ' embodiments disclosed, and that modifications and embodiments are intended to be included within the scope of the appended claims.
